+|--------------------------------------------------------------------------
+| Exit Status Codes
+|--------------------------------------------------------------------------
+|
+| Used to indicate the conditions under which the script is exit()ing.
+| While there is no universal standard for error codes, there are some
+| broad conventions.  Three such conventions are mentioned below, for
+| those who wish to make use of them.  The CodeIgniter defaults were 
+| chosen for the least overlap with these conventions, while still
+| leaving room for others to be defined in future versions and user
+| applications.
+| 
+| The three main conventions used for determining exit status codes
+| are as follows:
+|
+|    Standard C/C++ Library (stdlibc):
+|       http://www.gnu.org/software/libc/manual/html_node/Exit-Status.html
+|       (This link also contains other GNU-specific conventions)
+|    BSD sysexits.h:
+|       http://www.gsp.com/cgi-bin/man.cgi?section=3&topic=sysexits
+|    Bash scripting:
+|       http://tldp.org/LDP/abs/html/exitcodes.html
